&quo...Electrodes on the brain itself.<br /><br />Money quote:<br />&quot;The brain consumes a tremendous amount of the body&#39;s energy resources—it&#39;s only 2 percent of body weight, but it uses about 20 percent of the energy we take in,&quot; says Raichle. &quot;When we started to ask where all those resources were being spent, we found that the goal-oriented tasks we had studied previously only accounted for a tiny portion of that energy budget. The rest appears to go into activities and processes that maintain a state of readiness in the brain.&quot;<br /><br /><br />Link: http://www.innovations-report.com/html/reports/medicine_health/brain_signal_persists_dreamless_sleep_119473.htmlwins32767https://www.blogger.com/profile/01433187901681372369noreply@blogger.comtag:blogger.com,1999:blog-6198133958305421175.post-73059591104731151732012-02-21T14:32:11.180-06:002012-02-21T14:32:11.180-06:00Really?

Several studies recently imply that willpower and focus are limited.wins32767https://www.blogger.com/profile/01433187901681372369noreply@blogger.com
